Here, SCA infestation had led to the increased expression of four protease/proteinase inhibitors at 7 dpi in the sorghum SCA-resistant line, such as cystatin B (SbiRTX430.09G192300), cysteine proteinase (SbiRTX430.07G186000), aspartic proteinase (SbiRTX430.02G247500) and serine carboxypeptidase-like 27 (SbiRTX430.05G196500) (Supplemental Table S1). Here, CSTB is linked to autosomal dominant cerebellar ataxia.
